A team of 22 scientists from the Oregon State University-led Center for Oldest Ice Exploration, or COLDEX, is headed to Antarctica for the first field season in its pursuit of the Earth’s oldest ice and the climate records preserved in it.

COLDEX is a National Science Foundation-funded Science and Technology Center formed in 2021 and funded through a five-year $25 million grant.

On the Ground

COLDEX researchers expect to post weekly updates from the research site on the project’s website,
